I see people saying that the old flashcarts cant work in the DSi, and some companies have already released new flashcarts for the DSi.
I have even tested my Supercard slot one device in my DSi, and it will not work, as expected.

But why can't they work? Is it software? hardware?
Can I just plug my slot one device into a serial port on my computer and reprogram it to work? Or can some form of hacked firmware for the old flashcarts be made to make it work?

It is a combination of both I think and nintendo somehow checks the chip id or some parts of the software that is going to be started and than blocking it. That would explain the different behaviour the flashcard block is going to be displayed on the dsi.

- Some are not displayed when plugging it in.
- Some can be started up and then a message is shown.

I think the newer cards aren't blocked because the id and the software isn't listed in the dsi firmware, at the moment.

Can someone check what is the exact message which is printed when the flashcart boots up?

What was wrong with the explanation? What exactly the message is like doesn't care anyone. And the question after your post - older flash cards wouldn't work because the id / software of those are already integrated to be blocked in the firmware.

Thats it.

QUOTESo if the firmware was made to let in any form of ID, then the old cards will work?

Not any form of ID. Older flashcards are still blocked.

Ah and by the way, the error you get depends on the flashcard and the software / hardware is used in it. So you can't say US shows this and JP shows that. It depends on the card.

Hmm. fair enough. We will see what happens.
I'm just not sure about spending money on an Ace card if I can get my old cart working on the DSi. But because I'm impatient, ill probably just buy the ace card.

I think the newer cards aren't blocked because the id and the software isn't listed in the dsi firmware, at the moment.

The cards made specifically for the DSi aren't blocked because they report the ID and serial of an actual DS game - I seem to remember for the first DSi carts to hit the market it was some aquarium game.

I'm sorry but I don't believe that.
If i manufactured a flash card for the DS, I would release an entire new one and say the old one can't be updated to work with the DSi.
The DSi is blocking it because of something in its firmware, or the old flash cards just don't work with it because of some problem I don't know about.
Software has to tell hardware what to do. Whether its in Assembly, or just part of the flash cards OS/firmware. It's not being told to work, so it's not going to yet.
The hardware on the insides are the same as far as i can tell.

The hardware on the DS lite and DSi same on the inside? You meen except the new speakers, the new screens, the new memory and cpu, the wireing for the cameras, the added diod, the added SD-card reader and the removed gba-slot....
